“表征动量”（RM）是运动目标在运动方向上端点的错误定位。在视觉上，RM随着目标速度的增加而增加。然而，在听力中，目标速度的影响尚不清楚。在虚拟听觉空间中使用移动宽带噪声目标的感知范式，目标速度从25度/秒增加到100度/秒，RM从0.9度线性增加到2.3度。考虑到眼睛位置的影响也减少了方差。这些结果表明，RM可能是两种模式下相似的潜在机制的结果。(C) 2014年美国声学学会
"Representational Momentum" (RM) is a mislocalization of the endpoint of a moving target in the direction of motion. In vision, RM has been shown to increase with target velocity. In audition, however, the effect of target velocity is unclear. Using a perceptual paradigm with moving broadband noise targets in Virtual Auditory Space resulted in a linear increase in RM from 0.9 degrees to 2.3 degrees for an increase in target velocity from 25 degrees/s to 100 degrees/s. Accounting for the effect of eye position also reduced variance. These results suggest that RM may be the result of similar underlying mechanisms in both modalities.
